Craig,
The Jack Tray, Caster kit (steel wheels) and 3 Drip trays are included with the Lift. The hydraulic jack is listed at $495.00. They always have special pricing on these items at the Goodguys show in October.
Like LovDaBlues, I got the sliding hydraulic jack so servicing the brakes and/or removing all wheels is very easy. Use the sliding hydraulic jack for one end and use the jack tray with a couple jack stands on the other end.
Here's how I accommodated an 8' 6" height ceiling. I can stand under the car but I'm not very tall.
